process for reactivation of an acid ion exchange resin |
| abstract |
processes for reactivating an acid ion exchange resin, and for preparing and purifying an ethylenically unsaturated acid or ester, using process step c), and reactivated resin a process for reactivating an acid ion exchange resin is described. The invention relates to the treatment of an at least partially deactivated resin which has been deactivated upon contact with an impure ethylenically unsaturated acid or ester containing target impurities: reactivation includes the step of contacting the at least partially deactivated resin with an alcohol to thereby increase its activity. The invention extends to reactivation of a deactivated resin upon contact with an impure ethylenically unsaturated acid, ester or nitrile containing target impurities by contacting the at least partially deactivated resin with an alcohol and a carboxylic acid to thereby increase its activity. a reactivated resin and a process for preparing and purifying an ethylenically unsaturated acid or ester of the following formula: -R1-c (= (ch2) m) coor2 are also described. |
